Should we white-out/delete links to hijacked domains?

e.g. during the Tumblr purge, a lot of artists seem to have let their domains get hijacked by porn sites, etc. (e.g. triuni: triuni source:*triuni.tumblr.com)

We already can white-out (soft delete) domains in artist entries; could this be implemented for the Source field too?

I think just creating a tag for it is sufficient. This is basically just a subset of bad id, where the source is bad because the domain or account name was hijacked.
